Paper cone drivers/natural materials


I’ve been think recently about some post I read somewhere in which the OP complains about Wilson Audio’s use of doped paper pulp drivers for the cone material, saying that that’s not an acceptable material by today’s standards. Thinking about how meticulous is the design and execution of this company’s  offerings, this criticism just doesn’t seem valid. I’m sure if they found a better material, they’d use it. I’m sure they are designing for linear excursion within the pass band. I remember visiting an ex audio dealer’s house near Binghamton, NY, back in the early 80s when I was just a teenager. I remember him extolling the virtues of paper cones, and that way back then many manufacturers had experimented with others but kept coming back to paper. My opinion now is that many materials can be good candidates if executed well. Wilson is also using silk dome tweeters. My dad had very smooth and detailed sounding Philips silk dome tweeters back in the ‘70s in his homemade speakers. I say natural materials tend to hold their own and often prove superior. I have a cactus spine for my cartridge cantilever- my excellent Soundsmith Hyperion. Vandersteen uses extremely stiff and light balsa wood and carbon fiber in its top offerings. I can vouch for the excellent midrange in my 5A Carbon.

How much does driver material influence you purchasing decisions?

I have been told speaker cones should be lightweight and stiff.  I believe this relates to the amount of mass a driver has to move.  This, I would imagine lighter weight cone material that reduces flexibility might improve musicality.  Just a thought.  I am certainly not as knowledgeable as members in this group.

All speaker designs are compromises, like pretty much everything else in engineering. As regards Wilson, the company could use any material under the sun  for its drive units, so it uses the materials it does because within its design philosophy, they are the best fit for purpose.

One thing I will never forget is a slide from Focal sales and marketing discussing how they decide on new products and how they sell them.

One term stood out for me.  "Appearance of modernity." 

Appearance.

of.

modernity.

And I have no problem with Focal making their speakers desirable, at all.  That's their job.  But we as consumers also have to be aware that the appearance of modernity is an important selling factor that is not actually related to performance.  I can invent a speaker driver out of self-assembled graphite nano particles with heat sensitive carbon bubbles ... it is more modern.  Is it better?  Not necessarily related.
